Titanium BCGs

A 1" square of titanium is the exact same weight as a 1" square of commercial steel.........the main difference is the mechanicals - The Yields and Tensiles are much greater for Titanium.....than steel.....so you can use much less of it (titanium) for the same part integrity of steel.....thus making the part design lighter.)

That's not correct.

Titanium, generally speaking, is 45% lighter than steel, and 65% heavier than aluminum.

It is all about the mechanicals.....

Densities - periodic table of elements -4boxes to the left of FE"

Less achieves more ..and what is commercially available is alloyed with Alum or light metal)

Ti 6Al 4V -is bread and butter alloy Aluminum / Vanadium

That's fine. It still weighs almost half of what steel does (half is not almost the same). Which is what I was referring to when I quoted you (I've adjusted it now for better clarity). Titanium is less dense than steel.


Just curious, what do you mean by 'bread and butter alloy'?

Ti 6Al 4V is the most common titanium alloy, and is what the vast majority of "Titanium" products are made of. Most other Titanium alloys are for extreme use, alloyed appropriately for very specific roles. These Ti-alloys are usually found in Military and Aeronautics applications.

I know what it is. I machine it on almost a daily basis ;) Ti 6Al 4V is also known as 'Grade 5'.

I was curious as to what the 'bread and butter' comment was about. I gather 'bread and butter' = most commonly used?

Oh. well that's how I understood it. Describing something as the "Bread and butter of X" usually means it the most commonly used, seen or done in the specific example.
 
Titanium is best used for things like the SR71 Blackbird. Back in the earliest days of the SR71, the US had to buy titanium from the USSR under the guise of it being used for refrigeratiors. I'm not joking. USSR was the only source at that time.

And it was a HUGE national embarrassment for the USSR when the specs for the SR71 were declassified. The fact the they had unknowingly supplied their enemy with the materials to fabricate on of the most Top Secret (not to mention hugely damaging and potentially the most lethal) projects of the cold war made many people very mad.
 
Cool, lets hope they didn't use any chlorinated water in the coolant during machining or in the cleaning process. Cause we all know chlorinated water is forbidden in the aerospace industry. It has been known to cause stress-corrosion cracks resulting in failure of components that came into contact with chlorinated water.

So what you are saying is if I buy this bcg I can't take it swimming with me in the pool? Unacceptable, everyone swims with their ar15s. It is written in every manual, that one must swim in order to be a true owner of an ar15.

Hey Blast, I think I bumped into you at Area 51? :)

That unfortunate creature was a clone they used to install cyber implants on. They learned a lot from that experiment, and as a result I can read your mind from here, and everywhere. All the time. But you can't know that. ;)

I think he means he hopes it didn't touch the water before it gets to you.

Well exactly. Have you ever been attacked by feral rabid titanium? They are fierce. Chlorinated water drives them insane.

In case you were wondering I am trolling you there, I know exactly what he means. And I don't know the manufacturing methods or why it is even necessary to have a titanium bcg.
 
...And I don't know the manufacturing methods or why it is even necessary to have a titanium bcg.

That's the important part. In a reciprocating part such as a bcg, where the weight effects the function and often people are looking for heavy full auto bolt carriers, I really have to question the choice of titanium as a bcg material.

I would imagine it would need a different buffer spring than standard.
